param3d_properties - description of the 3D curves entities properties

### Description

The Param3d entity is a leaf of the graphics entities hierarchy.

  visible: This field contains the `visible` property value for the entity . It should be `"on"` or `"off"` . By default, the curves are visibles, the value's property is `"on"` . If `"off"` the curves are not drawn on the screen.
  data: This field contains the coordinates of the 3d curves. it is the matrix `[X,Y,Z]` such as `X(:,i)`, `Y(:,i)`, `Z(:,i)` contain the 3D coordinates of the `i`'th curve. This field contains the default `line_style` property value for Segs, Arcs, Rectangle and Polyline objects.
  line_mode: This field contains the default `line_mode` property value for the polyline. Its value should be `"on"` (line drawn) or `"off"` (no line drawn).
  line_style: This field selects the type of line to be used to draw lines . Its value should be an integer in [0 6]. 0 stands for solid, the other values stand for a selection of dashes (see `getlinestyle`).
  polyline_style: This field selects the way curve are drawn: interpolated (default), staircase, barplot, arrowed and filled modes are available through integer index [1:5].
  mark_mode: This field contains the default `mark_mode` property value. Its value should be `"on"` or `"off"` (default value).
  mark_style: This field contains the default `mark_style` property value. The `mark_style` selects the type of mark to be displayed. Its value should be an integer in [0 9] which stands for: dot, plus, cross, star, filled diamond, diamond, triangle up, triangle down, trefle and circle.
  mark_size_unit: This field contains the default `mark_size_unit` property value. If `mark_size_unit` is set to `"point"`, then the `mark_size` value is directly given in points. When `mark_size_unit` is set to `"tabulated"`, `mark_size` is computed relative to the font size array: therefore, its value should be an integer in [0 5] whith stands for 8pt, 10pt, 12pt, 14pt, 18pt and 24pt. Note that `param3d` and pure scilab functions use `tabulated` mode as default ; when using `plot` function, the `point` mode is automatically enabled.
  mark_size: This field contains the default `mark_size` property value. The `mark_size` selects the font size of the mark to be displayed. Its value should be an integer in [0 5] whith stands for 8pt, 10pt, 12pt, 14pt, 18pt and 24pt (see `getmark`).
  mark_foreground: This field contains the `mark_foreground` property value which is the marks' edge color. Its value should be a color index (relative to the current color_map).
  mark_background: This field contains the `mark_background` property value which is the marks' face color. Its value should be a color index (relative to the current color_map).
  thickness: This field contains the default `thickness` value of the lines used to draw the axes and the curves. It should be a positive integer.
  foreground: This field contains the color index used to draw the curves. Its value should be a color index (relative to the current colormap).
  clip_state: This field contains the default `clip_state` property value. Its value should be :
    `"off"` this means that all curves created after that are not clipped (default value).
    `"clipgrf"` this means that all curves created after that are clipped outside the Axes boundaries.
    `"on"` this means that all curves created after that are clipped outside the rectangle given by property clip_box.
  clip_box: This field contains the default `clip_box` property value. Its value should be an empty matrix if clip_state is `"off"`. Other case the clipping is given by the vector `[x,y,w,h]` (upper-left point width height).
  user_data: This field can be use to store any scilab variable in the param3d data structure, and to retreive it.
  parent: This property contains the handle of the parent. The parent of the 3D curves entity should be of type `"Axes"` or `"Compound"`.

### Examples

       set("figure_style","new") //create a figure
       a=get("current_axes");//get the handle of the newly created axes
       t=[0:0.1:5*%pi]';
       param3d1([sin(t),sin(2*t)],[cos(t),cos(2*t)],[t/10,sin(t)])

       a.rotation_angles=[65,75];
       a.data_bounds=[-1,-1,-1;1,1,2]; //boundaries given by data_bounds
       a.thickness = 2;
       h=a.children //get the handle of the param3d entity: an Compound composed of 2 curves
       h.children(1).foreground = 3 // first curve
       curve2 = h.children(2);
       curve2.foreground = 6;
       curve2.mark_style = 2;
